Good work!

Check the following code for question 9 and see how this works. make some changes in your code or try and understand what I have just send you!

from statistics import stdev
def st_dev(arr):
    
    total_elements = 0
    total_sum_elements = 0
    
    for num in arr:
        total_elements +=1
        total_sum_elements += num
    
    mean = total_sum_elements/total_elements
    
    deviation = 0
    
    for num in arr:
        deviation += (num-mean)**2
    
    standard_deviation = (deviation/(total_elements-1))**0.5
    
    return standard_deviation
